[0002] In the acid production process of copper smelting, the flue gas from the furnace and converter after electrostatic precipitator passes through two-stage dynamic wave scrubbers, and the acid produced is dirty acid. The dirty acid needs to be sent to the dirty acid sewage treatment station for treatment and then meet the discharge standards.

[0003] The existing technology mostly adopts a comprehensive recovery device for valuable metals from copper smelting waste acid, such as the one disclosed in announcement number CN203904420U. This technology includes a waste acid pump, a first filter press, a reaction tank, a reaction liquid pump and a second filter press connected in sequence, and the top of the reaction tank is connected to the first filter press and the bottom is connected to the reaction liquid pump. A steam heating coil and a stirring device are installed in the reaction tank, and the top of the reaction tank is also connected to a reagent tank via a metering pump. This technology has a simple structure, a short process, low investment and low operating costs.

[0028] Preferably, a fixed motor is built into the lower end of the second slide bar 7, and the output end of the fixed motor is fixedly connected to the rotating shaft 8, so that the stirring blade 9 rotates through the fixed motor, and the lower end of the body 1 is fixedly connected to a discharge pipe 10, through which the rhenium precipitate can be discharged.

[0029] The driving mechanism includes a guide slot 11, a first rack 12 and a second rack 13. The two guide slots 11 are respectively opened at the left and right ends of the inner wall of the upper mounting chamber 2.
